(a) How much charge can be placed on a capacitor with air between the plates before it breaks down if the area of each plate is 5.00 cm 2 (b) Find the maximum charge if polystyrene is used between the plates instead of air. Assume the dielectric strength of air is 3.00 × 10 6 V/m and that of polystyrene is 24.0 × 10 6 V/m.
